Abstract:
An improved mechanism for feeding paper sheets from a stack by suction includes a manifold provided with a plurality of spaced sheet pick up devices carried by the manifold and in fluid communication therewith. The improved mechanism also includes motion orginating devices supporting said manifold for lifting the same and the suction mechanisms and a paper sheet held thereby from said stack and feeding it into the entry grippers or the printing roll feed mechanism of the printing machine. The motion originating devices are adjustable to pick up sheets at different locations relative to their leading edges while the printing machine is operating as contrasted with the heretofore necessary steps of shutting down the printing machine and making a mechanical adjustment in the feed linkage. The adjustment mechanism of the sheet register control extends to a point convenient to the printing machine operator.
